Drawings for an elevator of 100,000- to 125,000-bushel capacity with plans for driveway floor and bins and single- or twin-leg configurations

These drawings reproduced from the records of Tillotson Construction Co., of Omaha, show the general-plan details of a 100,000- to 125,000-bushel, single- or twin-leg, reinforced-concrete elevator. 

To the left above, seen at the scale of one-eighth inch to one foot, is the cross-section of the structure. The main house has four tanks (silos) with internal diameter of 14 feet six inches and, at 100 feet in height, a 100,000-bushel capacity is achieved. At 120 feet, the capacity would increase to 130,000 bushels.

The cupola is marked as 22.0 feet high with a single leg and 30 feet 6 inches with two legs. Notations inscribed in the cupola space label the dust fan, distributor floor, automated scale, and cupola floor. The diameter of the leg’s head pulley is 60 inches.

In the main house, bins are numbered. From left to right, we see Bin 5, Bin 11, Bin 12, and Bin 15.

Above the driveway and work floor, a space that extends 17.0 feet accommodates the steel overhead-curtain-type door and electric truck-lift rails. The main slab is indicated below.

At the very bottom, we see a 13 foot 6 inch depth for the pit with a single leg or 15 foot 9 inch depth for a twin-leg setup.  

The driveway floor plan (center) is rendered at the scale of one-quarter inch to one foot. To the far left, we see a dock. The measure of 13.0 feet is given between the two tanks (Numbers 1 and 4). The driveway is 47.0 feet long–three feet longer than the main slab. It is 30.0 feet from the initial edge of the second dump grate to the driveway exit. The width is 13.0 feet. On the right are the electrical room, an electrically operated manlift, and a manhole.

The variation drawing, “Dvwy Floor Plan 2 Legs,” at the same quarter-inch scale, includes details for a twin-leg elevator. The note at bottom says, “Remainder of Plan same as with 1-leg.”

The Bin Plan at the right shows a 44.0-foot width. (So the main slab is apparently 44.0 x 44.0 feet.) At top we see a dust bin noted as well as bin draw-offs in the interior bins. A number of those bins are marked as 10 feet 4.5 inches across. Number 12 is 7 feet 11 inches wide. Number 16 is 12 feet 10 inches.

At lower right, the twin-leg variation drawing shows the distribution-control cable well–not indicated in other drawings we’ve posted–and the manlift and ladder well and manlift weight box.

The large tanks Numbers 1 to 4 are shown in counter-clockwise order from the upper right. At 100,000-bushels overall elevator capacity, Numbers 1 and 4 hold 11,996 bushels. Numbers 2 and 3 hold 12,066 bushels. At 125,000-bushel capacity, Numbers 1 and 4 hold 14,770 bushels. Numbers 2 and 3 hold 14,840 bushels.

The internal bins are at 100,000/125,000-bushel ratings as follows for single and twin-leg configurations: 

  • Bins 5 & 6: 4,555/5,7770 bushels
  • Bins 7: 2,207/2,400 bushels
  • Bin 8, 13, 14: 4,217/5,400 bushels
  • Bin 9 & 11: 6,030/7,730 bushels
  • Bin 10: 4,790/6,140 bushels
  • Bin 12 (scale): 4,452-4,014 (1-2 leg)/5,800-5,460 (1-2 leg) bushels
  • Bin 15: 4,858 (1-2 leg)/6,150 (1-2 leg) bushels
  • Bin 16: 4,790-4,465 (1-2 leg)/6,070-5,655 (1-2 leg) bushels 
  • Total: 103,042-102,279 (1-2 leg)/128,160-126,405 (1-2 leg) bushels

General Notes:

  1. If cleaner is installed in Bins #7-8-9 & 10 above the dv’y, add 2′ to D.F. [drawform] ht. to maintain capacity.
  2. Bin 5-6-8-13 or 14 can be used in conjunction with drier by placing hopper bottom half way up in bin.

The initials “TWM” in “DR BY:” box at bottom right indicate that Tillotson’s Ted Morris executed the drawings.

Drawings for an elevator of 150,000-bushel capacity with plans for work floor and bins

These drawings reproduced from the records of Tillotson Construction Co., of Omaha, show the general-plan details of a 150,000-bushel, single-leg, reinforced-concrete elevator.

To the left above, seen at the scale of one-quarter inch to one foot, is the cross-section of the structure. The main house has five tanks (silos) with internal diameter of 16.0 feet and achieves a height of 120 feet. No dimensions are shown for the cupola; the only notation in the plan says “automatic scale.”

In the main house are notes saying, “Up Leg” and “Down Leg. Other say, “Elect. Truck Lift” and “Dump Grate.” The driveway door is 13.0 feet high.

A precisely rendered rail car provides a fanciful touch on the far right, where it’s positioned at the load-out spout to receive a cargo.

At the very bottom, we see a 21.0-foot depth below the main slab.

The work floor plan (center) is rendered at the scale of three-sixteenths inch to one foot. We see that the whole structure sits on the slab measuring 50.0 x 47.0 feet. Internal diameter of the tanks is 16.0 feet. Notes show the locations of the electrical room, two manholes, dump grates, and at far right the dock.

The bin plan, also three-sixteenths to one foot, shows the five large tanks with Number 1 in the lower-right and the progression going counter-clockwise to Number 5 on the lower-left.

Sandwiched inside are Bins 6 through 16. We see that Bins 6, 8, 10 and 12-16 are marked as being 10.0 feet wide. Bin 9 is 7 feet 6 inches across. Bin 14, on the far right, is 13 feet 9 inches across. Bin 16 is labeled “Dust Bin.”

The large tanks Numbers 1 to 5 have capacities of 17,650 bushels. The internal bins are as follows:

  • Bins 6-7: 5,300 bushels
  • Bins 8 & 10: 6,790 bushels
  • Bin 9: 6,000 bushels
  • Bin 11: 6,540 bushels
  • Bin 12: 2,640 bushels
  • Bin 13: 5,300 bushels
  • Bin 14: 8,220 bushels
  • Bin 15: 7,980 bushels
  • Bin 16 (Dust Bin): 930 bushels

Unlike any of the other plans we have, this one is dated. One entry in the lower-right says, “Rec’d 3-3-58.” There are two other illegible dates, but at very bottom another date shows 3/31/58.

The initials “TM” would seem to indicate that Tillotson’s Ted Morris executed the drawings.

Drawings for an elevator of 200,000-bushel capacity with bin plan and schedule

The present drawings that are reproduced from records of the Tillotson Construction Co., of Omaha, show details of a 200,000-bushel, single-leg, reinforced-concrete elevator

To the left above, seen at the scale of one-eighth inch to one foot, is the cross-section of the structure. The main house has eight tanks (silos) with internal diameter of 15 feet six inches and achieves a height of 120 feet. The cupola is 30 feet six inches high. At the bottom, we see a depth of 15 feet three inches below the main slab.

In the cupola, we see notations for the distributor, distribution floor, and automatic scale.

Below, numbers of the large tanks and smaller interior bins are noted. The driveway and rolling door are shown above dump pits Number One and Two. The driveway is 12 feet wide, the door is 13 feet high, and a 17-foot distance extends between driveway floor and driveway roof.

Other notes in the lower-right indicate the work floor, back pit, and a track conveyor to be installed at a future time.

Outside the elevator’s wall is a load-out spout for rail cars and the inscription “Track,” showing where a car draw up to be filled.

Ratings for the bin schedule are cut off due to the limitations of our scanner bed and the 11×17-inch sheets that were copied from blueprints by Uncle Tim Tillotson.

The schedule has the large tanks, Number One through Seven, at 16,880 bushels each. Number Eight is 15,495 bushels. Internal bins nine through 20 range in capacity from 3,980 bushels (Number 19) to 6,665 bushels (12 and 14).

The whole structure sits on the slab measuring 48.5 x 62.0 feet.

Number 21, which can barely be seen in the Bin Plan, is an ovalized chute that stands just outside the accommodations for the electrically operated man lift. “Down” is inscribed to the left of the lift, and “loader” and “up” are to the right.

The Bin Plan and Work Floor Plan are shown at the scale of three-sixteenths inch to one foot.

From the bottom, notes in the Work Floor plan show “Trucks” entering in the direction of the arrow to the two dump pits. Additional notes say “Rails for the 7 1/2 H.P. overhead Electr. Truck Lift” and “12′ wide x 13′ high Overhead Steel Curtain Type Door (Opp. end same).”

At far right, notes say “Track Door” and “RR Siding.”

The stairway inside Number Eight is indicated with the note “Down to Bsm’t.” And this stairway is the reason for the tank’s capacity of 15,495 bushels as opposed to the 16,880 bushels of the others.

Drawings for an elevator of 250,000-bushel capacity with bin plan and schedule

Here in sharp detail, at the scale of one-eighth-inch to one foot, we have drawings for a 250,000-bushel Tillotson elevator. The bin plan gives capacity at 252,300. Tillotson Construction Co. built many elevators of this capacity, although we can’t determine how many of them adhered to the drawings we see here.

The level of detail is exceptional. In the cross-section, we see a stairway and its railing, an interior ladder (apparently in the manlift channel), basement window sash, 7.5-horsepower Ehrsam truck lift and hand-operated rolling curtain door, port for inspection of the leg, and the 72×14-inch head and boot pulleys. A note on the lower left says “Future 3 hp – 14″ conveyor,” and broken lines indicate its course. Another note to the left indicates “10[-inch] well casing”. Another note near the top of this channel says, “Rad. Dist. to 3 bins & Loading Spout & Driveway.” This we take to mean radial distribution.

The “car” at far left presumably represents a rail car.

The drawform walls of the tanks (silos) are 120 feet high.

The cupola is 40 feet high and 50 feet 3 inches long. We learn that inside it, a 40-horsepower Howell head-drive turns the head pulley at 42 revolutions per minute. The leg’s 14-inch, six-ply belt has cups of 12×6 inches for a leg capacity of 6,300 bushels per hour.

Another note and a zig-zag arrow indicate “Top of Manlift Travel” and two-horsepower Ehrsam manlift.

Detail drawings inside the cupola show the intake and exhaust for the three-horse exhaust fan. Made of 14-gauge steel, the spouting is 10 inches in diameter. Another notation and additional broken lines indicate “Future 2,500 bu. Hopper Scale.” This is near the automatic scale and the grate platform.

Other plans–each with its own details–are for the roof and the cupola floor, bins, foundation, and work floor and driveway.

Drawings for an elevator of 254,000-bushel capacity with bin plan and schedule

The drawings we have in hand from Tillotson Construction Co. include this plan for a 254,000-bushel reinforced-concrete grain elevator.

While the company built a number of elevators rated at 250,000 and 252,000 bushels, these were likely based on different drawings.

Otherwise, the records show just one elevator of 254,000 bushels–that’s 254,104 bushels, to be exact. It was built in 1950 at Palmer, Iowa.

A 252,000-bushel elevator went up the year before at nearby Pocahontas, Iowa.

The Palmer job was a single-leg elevator with 115-foot-tall tanks (silos) and a cupola measuring 23x60x40 feet. Fully loaded, its gross weight was 12,975 tons.

A dryer bin was included at the time of construction.

Drawings for an elevator of 314,000-bushel capacity with bin plan and schedule

Records show that Tillotson Construction Co., of Omaha, built a few reinforced-concrete elevators with capacity of more than 300,000 bushels. The drawings posted here depict the outlines of a 314,000-bushel elevator with two legs.

The first was a twin-leg, 350,000-bushel job on an original plan at Farnsworth, Tex., in 1945.

Next–310,000 bushels, also on an original plan–came four years later, in 1949, at Dalhart, Texas.

1950: Canyon, Tex., and Bellwood, Neb., on a shared plan for 320,000 bushels. That same year, Rock Valley, Iowa, came close at 296,130 bushels. And the Vinton Street terminal, in Omaha, was completed at 382,880 bushels.

1951: Sunray, Tex. added a 550,000-bushel annex with 14 tanks (silos) of 20 feet in diameter. Hereford, Tex., welcomed a 300,000-bushel elevator on its own original plan, and York, Neb., did the same–also an original plan–with 336,000 bushels that same year.

1953: Cherokee, Okla. (original plan) 309,400 bushels; Ralston, Iowa (original plan) 537,500-bushel annex with eight tanks of 28 feet in diameter reaching to 115 feet in height; Estill, S.C. (original plan) with 10 tanks of 18 feet in diameter reaching to 120 feet. (The year earlier, Tillotson had built 225,000 bushels of storage at Estill.)

1954: Orienta, Okla. (original plan) 312,000 bushels with 10 tanks of 20 feet in diameter towering 114 feet nine inches; Bellwood, Neb. (original plan) 340,000 bushels with 10 tanks of 20 feet in diameter and 130 feet in height; Iowa Falls, Iowa (Bellwood plan) 321,000 bushels of 122 feet (no other information is included in the records); Glidden, Iowa annex of 331,000 bushels (incomplete entry); Ensign, Kan. annex (original plan) 319,830 bushels with 11 tanks of 19 feet in diameter and 118 feet in height.

Tillotson built no elevators of such great capacity in 1955, the year our records end.

“Sorry these are printed with margin on wrong end,” write Uncle Tim Tillotson after copying the elevator plans in his possession.

“Was busy unfolding and folding the old originals for the [printshop] guy because he tore the first print I handed him (on fold line) just unfolding it. They came out of printer 3 feet long. Didn’t realize Boo-Boo till I got home. Too much $ to re-do!”

Nevertheless, we benefit from Uncle Tim’s efforts and from our cropping tool, which lead to this series of posts with all plans from that printing session.

Specifications from Alta, Iowa and drawings of a likely model for that elevator

In response to a reader’s question, we are posting some basic specifications of the Alta, Iowa, elevator that Tillotson Construction Co. built in 1950. (Plans alter between “Tillotson Contracting Co.” and “Tillotson Construction Co.”

The drawings seen above are Tillotson’s standard plan for a 250,000-bushel elevator with eight tanks (silos).

Capacity at Alta was 246,070 bushels. The eight tanks of 18 feet in diameter sat on a main slab of 60.0 by 73.5 feet. The driveway was 13 x 15 feet.

The walls of the tanks rose 115 feet from the slab, and they were topped by the cupola measuring 23.0 feet wide, 61.5 feet long, and 39 feet high. That brought the structure up to 154 feet–quite imposing.

Art Parrish and his family went from one Mayer-Osborn elevator job to the next through the 1950s

Mary Ann (Parrish) Davis is the daughter of Art Parrish (b. 1921-d. 2012), who was a superintendent for Mayer-Osborn Construction Co. The family–Art, Flo, Alice, Mary, and their dog, Tuffy–went from job to job, living for weeks or months at a time in places ranging from Wyoming to New York. They had many marvelous, dramatic, and even tragic experiences. Mary was married 44 years to James Davis until he passed away in 2007. They had three children. Today she is known as Mary Mentel from a subsequent remarriage in 2011. We spoke to Mary by phone from her home in Oklahoma City on May 11, 2021.

Art Parrish

Mary: When he [Art] started working on elevators, he was only 18 and had just married my mom and worked as a laborer. In fact, his first day of work, he worked for his father-in-law, John Berle Fowler [Mary’s grandfather], he climbed into a big storm drain and fell asleep, so he [Fowler] fired him. After he forgave him and gave him another chance, he taught him to read blueprints. He [Art] worked real hard, and after a certain time he became a carpenter. When he was working as a carpenter, he was called to the Army in November of 1944. So from 1940 to 1944 he worked as a laborer and carpenter. Called into the army during the war, he was injured and sent home. He went back, and the war was over: they dropped the bomb. After the war he went back to work on an elevator because he already had experience and could read blueprints. He always thanked his father-in-law for that. It was in 1945 when he got out of the Army and  started working on this big job that was in Enid, Oklahoma. (That was his hometown.) He worked as a carpenter. His superintendent was Bill Grammar. So my dad was a carpenter for a year. Bill came to him and asked, “When this job is done, I have a small job in Oakland, Kansas. Do you think you can handle a foreman’s job?” The company from Hutchinson, Kansas, sent Bill up there. My dad said he didn’t know if he could do it, but sure would like to give it a try. Bill said it would pay $1.50 an hour. Now this was in 1946. The laborers got $1 an hour, the carpenters got $1.25, and a carpenter foreman got $1.50. Bill had been a superintendent for many years and–he was as old as his [Art’s] dad–and he only made $150 a week as a superintendent. He was on a steady salary. That’s how things were in those days. But you could buy a new car every other year, which my dad always did that. He said with that kind of money, things were cheap then. 

There was an old man that worked with my dad. His name was Roy Snodgrass. He kind of treated him like a son. My dad was still limping. He’d been shot in the leg a couple of places with a machine gun in the war. This old man said, “Are you getting your pension?” My dad said no. Well, he forced him to go downtown and sign up for that. My dad was always thankful. He said one day it was raining, and when that happened they would go into the toolshed and play poker. And Roy told my dad, “Come on, we’re going to go get you signed up for your pension.” So they did, and about a year later he started getting his pension in 1946. This doesn’t have anything to do with elevators, but his pension was $42 a month. By 2006 it was $800 a month. But then in 2007 the government cut it in half for any vets over 80 years old, which I thought was really sad. 

Myrl Davis, who was Mary’s father-in-law, with crew at an undetermined job site.

He said he never did see Roy again after that job. Then from 1946 to 1952, Art worked for six years as a carpenter foreman. He was all over the Midwest on different jobs, all grain elevators. There was just one time he worked on a cement plant. Then he was hired in 1952 as a superintendent when I was eight years old. 

My grandfather, J.D. Fowler, worked construction on the elevators. My father-in-law, Myrl Davis, he worked for Mayer-Osborn. In 1952 we were in Rudd, Iowa. It was population 400–you probably never heard of it. The elevator was the only tall building in town. It was really a big deal. There were about 10 kids in my third-grade class, and my dad invited the teacher and the children to come up on top after it was finished. So that was a big deal for me and my class. There was a  small elevator on the outside of the [grain] elevator. That’s what we got in to go up. I think he called it a manlift. I don’t know if they used ropes or it was electric. On that job his foreman was Ray Rogers. There were like three families of us that traveled, and we would see each like every other year. We kind of grew up together. Myrl Davis, Ray Rogers, and Art Parrish–those three families. And I ended up marrying Myrl Davis’s son and was married for 44 years before he died. He had one sister and 10 brothers, and all the boys were named with girls’ names. One of the brothers worked on one of my dad’s elevators, I’m not sure which one, but he had a heart attack on top. They all died before they were 65 of heart attacks; they were all kind of heavy drinkers. The one that died on top, he had a heart attack on top of the elevator. My dad carried him down. By the time he got he down, he was gone. My dad never told me these things till I was old.  

We went to Rochester, New York, and that was where my dad worked on the cement plant. 

[Mary raises the question whether it could have been a Mayer-Osborn Co. job, and we discuss the range of their work throughout the Plains, down to Texas, points in Iowa, and even Tempe, Ariz.] 

My dad worked an elevator in Tempe, Arizona, when I was in first grade. If I was in first grade it would have been probably 1948 or 1949. I remember Tempe. When we drove into town everybody was wearing coats. It was like 65 degrees and raining. Everybody was shivering. We were laughing at them. I learned to ride a bike in Tempe. I liked it there. 

Flo, Art, Mary (front), and Alice and an Oldsmobile

After Rochester–that’s the first place I ate pizza; it was wonderful–we went to Iron Mountain, Michigan. It was way out in the country and really cold. We went ice fishing. We saw the biggest ski jump in the whole world. And then when I went to school there, I went in and the teacher told them I was from New York, and they all applauded. This was a little bitty country school and I guess they thought I was from New York City or maybe they thought everybody from New York was a celebrity.

In 1955 we lived in North Canton, Ohio, and built an elevator there.  

In 1958, when I was 14, the elevator we built in Limon, Colorado, was right across the field from where we lived in a trailer court. So I saw it go up, and that was really interesting. It seemed like it took most of the summer for the foundation. When they poured that, my dad always worked–even when he was superintendent–he worked 48 hours straight when they poured that concrete. The other guys would be on a shift, eight or 10 hours, but a lot of times he had to call people in to help because they wouldn’t show up. He started getting ulcers because he was worried a lot about different things. I’d walk outside at night, after dark, and you could see across the field from our trailer court, it was bright out there. They’d string lights above and have floodlights shining down so they could keep working constantly for 48 hours. Then they’d get to go home and sleep for maybe a day so it would dry real good. Dad was superintendent, Myrl Davis was foreman. A lot of times on different jobs, either Myrl or Ray Rogers would be foreman. Some jobs he had both of them working, one as carpenter, one as foreman.  I was surprised after they did that foundation. It shocked me how fast that elevator went up, like one day it wasn’t there and the next day it was. Of course then they had all the inside and everything else to do. But it just went up so fast. I always knew he was on a time limit because they were on a contract, and if they didn’t finish within a certain time, they didn’t get as much money and they got in big trouble. My dad was real good about getting it done and doing it well. He said as far as he knew, in his whole life, he never had problems with his elevators. A lot of different companies, it crumbled or they had problems. His were always really well built. 

Mary Ann Parrish Davis, now Mary Mentel

I’m not sure where we were going in 1954, but our trailer turned over when we were pulling it on a wet two-lane road in Wyoming. These two big semi-trucks passed us real fast, and from the air pressure the trailer started weaving and my dad lost control and it turned over. It was the only one we had. It was brand-new, extra wide and long and like a split-level. That was a scary time, real traumatic for my parents. We had to live in apartments for a while until we bought a used trailer. I think back on my favorite Christmas. It was when that happened. Because we had no money, we were in a motel room. So they got these big Christmas stockings full of toys and candy. And the next year we made our own Christmas decorations. 

The last job that my dad worked on was in Commerce City, Colorado. That’s near Denver. It’s like a suburb. That was in the 1960s. He quit building the elevators. He painted the old ones, put the names of the towns on them. They stayed in Denver because my sister and I had gone to over 30 schools when we were growing up. [Art and Flo were divorced during this period in Denver.] Even after he retired my dad never quit working. He built his own house. He poured patios and driveways for people all around Denver, and he painted houses with his stepson and his family. He loved getting together with Ray Rogers and Myrl Davis and laughing and talking about old times. 

After we kids got married and moved out, he married my stepmother. They moved back to Commerce City. She had a house there. 

Art Parrish

My dad died in 2012. He was 91 years old. He was told he had cancer in 2007 and had six weeks to six months to live. My mother died, my husband died, my stepsister died. My dad was still alive. I was grieving everybody, and I said, “I’m not going to grieve him any more.” He lived until 2012–that much longer. The doctor said, “What do you want to do with the time you’ve got left?” He said, “I want to make a liar out of you.” And he did.
